Answer:
They sure can. It can happen for a lot of different reasons depending on the person and their psychological makeup.
But in your case a lot of these feelings you're having are probably because you miss your boyfriend so much when he goes away, which is perfectly natural. On the other hand you don't want these feelings to make you too upset so I'd suggest going out and getting involved in something whenever he goes away so that you can keep these feelings from becoming overwhelming.
It's normal for feelings of sadness and anxiety to get worse when a person is by themselves, so when he leaves call up a friend, go out with a friend or a family member, visit someone or just get out and do something that will keep you busy and involved for a time until you start to feel more anchored and less upset.
If you feel that these feelings are getting worse or if you find that you feel this way during other times in your daily life, then it may be helpful to talk to a counselor about this so that they can help you find some better ways to cope.
I wish you all the best, take care :)
it sounds like you do have separation anxiety. you have a fear of being alone. Which all of do every now and then. My kids have been gone for three weeks and I find it hard, like separation anxiety symptoms.
Me, too. I am also a 19 year old boy. I am scared to leave my mom and dad sometimes. I am not ready to live on my own yet for several years. I have a part time job, and I attend college, which I have an aide and extensive emotional and social support for. I plan on hopefully getting a girlfriend soon. My parents are always there to support me and never leave me to be alone or afraid. I am a happy boy.
